Hazardous gas detection
· Ammonia gas detection: Ammonia gas is produced during chemical processes such as fertilizer production. The gas detector can monitor the ammonia gas concentration in the environment in real time. When ammonia gas leaks, the detector will quickly sound an alarm to remind staff to take timely measures. For example, in a fertilizer plant, after installing ammonia gas detectors, many poisoning accidents that may have been caused by ammonia leaks were successfully avoided.
· Chlorine gas detection: Chlorine is used in the production of chlor-alkali chemicals and other industries. Chlorine is a highly toxic gas. Gas detectors can accurately detect their concentration and prevent leaks from causing casualties and environmental pollution. For example, a chlorine gas detector is installed in the liquid chlorine storage area of a chemical plant. Once chlorine gas leaks, the detector will immediately alarm, ensuring the safety of surrounding personnel.
Process monitoring
· Reactor monitoring: In chemical reactions such as organic synthesis, changes in gas composition and concentration in the reactor reflect the reaction progress. The gas detector can be installed on the top or side of the reactor to monitor the gas generated during the reaction and determine whether the reaction is proceeding normally. For example, a gas detector is installed on the reactor of a pharmaceutical factory to monitor gas changes during the reaction in real time, ensuring the quality of pharmaceutical production.
· Storage tank monitoring: Storage tanks of chemical companies are used to store various hazardous chemicals, such as crude oil, gasoline, etc. in the petrochemical industry. Gas detectors can be installed around and on top of storage tanks to monitor the concentration of flammable gases and toxic gases in the storage tanks and surrounding environment to prevent leaks from causing fires, explosions or poisoning accidents. For example, a combustible gas detector was installed in the storage tank area of an oil depot, which effectively ensured the safe operation of the storage tanks.
Environmental monitoring
· Exhaust gas emission monitoring: The exhaust gas emitted by chemical companies contains harmful gases such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. The gas detector can be installed at the exhaust outlet to monitor the concentration of pollutants in the exhaust gas in real time to ensure that the company's emissions comply with environmental regulations. For example, a chemical plant installed gas detectors at exhaust outlets to monitor exhaust emissions in real time, adjust production processes in a timely manner, and reduce pollutant emissions.
· Factory environment monitoring: In the chemical plant area, gas detectors can be distributed in different areas to monitor the concentration of harmful gases in the air and understand the distribution and diffusion of harmful gases in the factory area. For example, in a large chemical industry park, multiple gas monitoring points are set up in the park, and gas detectors are used for real-time monitoring to ensure the environmental safety in the park.
Security management
· Establish a detection system: Based on the data provided by gas detectors, chemical companies establish a complete gas detection system and stipulate the time, location, frequency and method of detection. For example, a chemical company has formulated a detailed gas detection system, requiring workers in each shift to use portable gas detectors to detect the working area before work to ensure a safe working environment.
· Emergency response support: When an accident such as a gas leak occurs, gas detectors can quickly detect the concentration and composition of on-site gases and provide accurate information to emergency rescue personnel. For example, a hydrogen leakage accident occurred in a chemical plant. The on-site gas detector quickly detected the hydrogen concentration and distribution range, which provided key basis for rescuers to formulate a rescue plan and enabled the rescue work to be carried out efficiently.
Equipment maintenance
· Internal testing of equipment: Before maintenance and overhaul of chemical equipment, use gas detectors to detect gas components inside the equipment to ensure that the concentration of harmful gases in the equipment is reduced to a safe level. For example, before overhauling a chemical reactor, the staff used a gas detector to detect the inside of the reactor and confirmed that there was no harmful gas before entering the maintenance work.
· Leak detection: Conduct regular or irregular leak detection on equipment to find potential leak points. For example, a chemical plant uses portable gas detectors to conduct regular inspections of pipeline connections, valves and other parts, promptly discovering and repairing multiple gas leaks, and avoiding safety accidents caused by leakage expansion.
